Fund Quality Breakdown

Quality Breakdown

Barclays uses the "middle rating" of Moody's, S&P, and Fitch to determine a security's index classification. If only two of the agencies rate a security, then the most conservative (lowest) rating will be used. If only one rating agency rates a security, that one rating will be used. Where there are no security level ratings, an issuer rating may be used to determine index classification. Barclays Index breakdowns are grouped into larger categories. For example, AAA+ and AAA are listed as Aaa; AA1, AA2, and AA3 are listed as Aa, etc.
